Security – Chapter 2

Malware is software that enters a computer system with the user's knowledge or consent and then performs an unwanted and harmful action.

Once the malware reaches a system through circulation, then it must embed itself into that system.

Two types of malware have the primary trait of circulation. These are viruses and worms.

A polymorphic virus changes its internal code to one of a set number of predefined mutations whenever it is executed.

A virus self-replicates on the host computer and spreads to other computers by itself.

A remote access Trojan has the basic functionality of a Trojan but also gives the threat actor unauthorized remote access to the victim's computer by using specially configured communication protocols.

A rootkit can hide its presence, but not the presence of other malware.

Social engineering impersonation means to masquerade as a real or fictitious character and then play out the role of that person on a victim.

Phishing is sending an email or displaying a web announcement that falsely claims to be from a legitimate enterprise in an attempt to trick the user into surrendering private information.

Vishing is a false warning, often contained in an email message claiming to come from the IT department.
